Hitch slides automatically as you drive to give you 22-1/2" of additional clearance for tight turns. A wraparound jaw provides a smooth ride and a locking bar offers added security. Pivoting head allows easy hook up and helps to limit chucking.

Note: This fifth-wheel trailer hitch is not compatible with Sidewinder or Revolution king pins. Do not use any device that changes the pivot point of your trailer's king pin with this hitch.
Automatic Slider Makes Cornering Easy
A slider helps to eliminate clearance problems during slow-speed turns. When you are towing a fifth-wheel trailer, your hitch must be situated on the cab side of your truck's rear axle. However, at slow speeds you can use a slider to slide the fifth-wheel hitch (and the trailer) toward your truck's tailgate and past the rear axle, creating enough space between the cab of your truck and the trailer to permit less-restricted turning.
Normally, you'd have to get out of your truck and pull a lever to release the slider before every turn, but what if there was an automatic system? Imagine having 22-1/2" of extra clearance while towing your fifth-wheel trailer. Now imagine having this without needing get out of the truck to move your slider. The Demco Hijacker Autoslide makes this fantasy a reality. The Autoslide automatically glides back smoothly when you make a sharp turn so you can maneuver effortlessly around tight corners within campsites and parking lots.
The Autoslide has a built-in roller-and-guide assembly that allows for smooth, controlled, and automatic movement. As your truck turns, this assembly also turns. When the assembly turns, an arm in the base of the hitch moves down 1 of 2 tracks in the interior of the base. This action causes the head to be pushed down one of the exterior tracks in the base. So, when your truck makes a sharp, slow-speed turn, the roller-and guide assembly inside the Autoslide forces the hitch head to slide down toward your truck's tailgate in a smooth, controlled motion. This way, any time that your truck turns more than 10 to 15 degrees, the Autoslide will ensure that there is enough clearance for your trailer to complete the turn as well, and it will do so without any jerking or binding.
In order for the roller-and-guide assembly to function as designed, the pin box must be stabilized on the hitch head. Normally in a 5th-wheel hitch, the king pin moves inside of the hitch head so that the trailer can turn. With the Autoslide, the king pin remains fixed inside of the jaws of the hitch and it is the hitch head itself that turns. This is thanks to the capture brackets on the sides of the head that brace the pin box from both sides to hold it in place on top of the hitch head.
To stabilize your pin box on the hitch head, simply push the capture brackets up against your pin box once the trailer is coupled and tighten the outer bolts and the inner jam nuts. The Autoslide head and brackets will fit standard pin boxes that are between 12" and 14" wide. If you have a Glide Ride, Mor Ryde, Trailair Tri Glide, or 5th Airborne pin box, you must install a special locking plate (sold separately) as well.
When you straighten your rig out again and your trailer moves back in line, the hitch head will rotate back to center and slide back toward the cab into the straight towing position.
Secure Wraparound Jaw with Locking Bar
The single-piece, strong wraparound jaw completely surrounds your trailer's king pin for 360 degrees of contact. This wraparound jaw provides a more secure connection than standard 2-piece jaws that close in on the king pin from the sides. The increased jaw-to-king-pin contact on the Autoslide offers tighter tolerances around the king pin, which minimizes both rattle and chucking, for a smooth, quiet ride.
A 3/4" solid steel locking bar spans the area in front of the jaw. This bar provides an added barrier of protection against accidental disconnection so you can have peace of mind that your trailer is secure. The locking bar is attached to the jaw and to the spring-loaded handle. The bar automatically locks when the jaw closes around your king pin.
Double-Pivot, Cushioned Hitch Head
The double pivoting, cushioned head improves your towing experience dramatically by helping to reduce jarring and unwanted noise. Built-in pins allow the hitch head to pivot back and forth and side to side. And hooking up is easy because the hitch head will automatically pivot to the proper angle when it comes into contact with your pin box.
Three polyurethane dampeners help to cushion the movement from the pivoting head and to reduce towing noise. Two of these dampeners are built into the head assembly to cushion the head's side-to-side pivoting. The third dampener cushions the back-and-forth motion and must be installed in the hitch prior to use. Installation of this third dampener is easy - simply press the dampener up into the pre-drilled hole underneath the hitch head.
Easy Installation
The Autoslide hitch is specially designed to fit the included Demco UMS custom underbed mounting kit. The hitch comes pre-assembled for an easy installation. All you have to do is bolt on the side plates and attach the head to the hitch base.
The side plates have 2 functions. They contain the feet that fit into the receivers in your truck bed, and they allow you to raise or lower the hitch head to better match your pin box height. After you choose your desired height setting, simply bolt the side plates to the hitch base with the included hardware. Then lower the hitch into the 4 UMS receivers in your truck bed. Turn the handles to lock the feet into the receivers and secure the handles with the included safety pins. The hitch can be removed to give you full truck bed access. Simply remove the safety pins, turn the handles to unlock the feet, and lift the hitch out of the receivers.
Clearance Formula for Short Bed Trucks
Use the formula below to ensure there will be enough space between your truck cab and trailer when executing a 90-degree turn.
(A+B) - C = Clearance
A = Distance from the center of fifth-wheel hitch jaw to truck cab
B = Length of Travel (22-1/2")
C = Width of trailer divided by 2 (to get half)
For example: If the distance from the center of the hitch to the cab is 36", 36" + 22" = 58". If your fifth-wheel trailer is 102" wide, take half (51"), then plug in: 58" - 51" = 7" of clearance.
Note: At least 4 inches of clearance is recommended to safely execute a 90-degree turn.

Today we're going to take a look at the replacement side plates for the Demco Hijacker Autoslide fifth wheel trailer hitches, and this is for the underbed mount. Now this will replace the side plates that came standard with your Demco Hijacker Autoslide underbed fifth wheel trailer hitch. They are designed to bolt onto your hitch base so that you can attach your hitch to the custom underbed rails. This is designed to fit the 13,000 pound Hijacker, Part Number DM8550041. It also fits the 18,000 pound Hijacker, DM8550022, and the 21,000 pound Hijacker, DM8550037 models. This is a simple bolt-on installation to your hitch base. There are multiple rows of bolt holes on these side plates and on your hitch base, so depending how you line them out, it will let you adjust the hitch height.
The hitch height settings will go from either 15-1/2 inches to 16-3/4 and 18-1/4, so you have your choice of those three settings to get your trailer and tow vehicle as level as possible. These do have a rust-resistant black powder coat finish. They are an all-steel construction. It does include the instructions. It will include the mounting hardware, and it also includes two 1/4-inch spacers and two 3/8-inch spacers, and the spacers are used for adjusting your hitch mount with the bed pockets of your truck, and this part is made in the U.S.A. The way that these would open up is you just pull the clip, pull the pin out, and you can see each one of these will rotate out, and when you rotate those out, it will let you drop it into your underbed mount, and then once there, you just turn this back in to lock it, and then put your clip right through there just like that. This part is made in the U.S.A. That should do it for the review of the replacement side plates for Demco Hijacker Autoslide fifth wheel trailer hitches with the underbed mount..
The hitch is great. I installed it myself and it worked very well pulling a 5th Wheel Trailer across the country last year. I have learned however that one must start out from corners slower to avoid a large "clunk" as the hitch slides in the frame per the inherent design. Great Product!
This hitch has worked great for the last year. I can put the truck a full 90 degrees to the camper with no issues on my standard bed (6'8") truck. I never have to worry about taking out my back window either going forward in tight turns or backing up. The only negative is the weight of the hitch. I use an electric hoist to take the hitch in and out of my truck. Very quick and easy with the OEM puck system. The guys at Etrailer were great to work with. Best price I could find and delivery was quick and easy.
Worked out great. I used the hitch for my camper right after I installed it. However, I did break one of the bolts when installing it, which is OK. I just switched to grade 8 bolts which is better anyways. I love the fact that Demco hitch unlocks when you pull the lever regardless of weight on it. Compared to my previous Mopar hitch you had to get at the right weight pressure to unlock it.
The new lower base for the Demco hitch arrived on Tuesday via Freight it was a great interaction the driver I actually knew from a previous delivery, me and a friend were able to lift the old one out of the bed of my truck and install the new one today and all I have to say is...
PERFECT FIT!
It appears that Demco has already redesigned the lower base compared to my original one to prevent this problem from happening again. I was actually kind of shocked to see that upgrade and change.
I cannot say enough good words about you with etrailer and Demco working with me to get this problem solvedm Yes it took a little bit of work, ultimately this time we got it. I cannot thank you guys enough.
My friend and I will be finalizing the installation and getting it locked down to the bed with a few custom spacers for the lower rails this weekend.
Here are a few pictures of the installation resuming. If I remember , when I finally pick up my new camper, I'll send some pictures along too. Have to give credit where credit is due . Not sure of you have a customer wall at HQ. I know we had one in my old shop.
Anyway.. thank you again .
Has to do a little assembly, really easy. Tows super nice, when turning does move towards the back. You’ll need to adjust the guides for the fifth wheel.
Love this hitch. While it is heavy it provides the stability and auto slide capability that I need to comfortably drive my 5th wheel thousands of miles. I have never had my 5th wheel contact my cab no matter how tight I turn.
This product definitely gives me more availability for tighter turns that I was looking for. Second trip we took one of the pins popped out of the puck locking mechanism. Our last trip to Wyoming the spring pin that holds the head onto the frame was laying in my pick up box, bought a new spring pin clip that’s a little tighter, that seem to fix that issue. It would be good practice to go over the entire hitch of all mechanisms latches and secure pins before traveling. Seems with the moving and shaking, they may have a tendency to loosen a bit overtime.
A very nice hitch. If you have a bed carpet or a bed liner it may require Un shimming the locking pins. I have a bed carpet and I had to stand on the back corners to get the pins to engage the bed pucks. Not really a big deal. It is very heavy so I assembled it in the bed of the truck. I would highly NOT recommend doing it this way except if you are by yourself. Get a chain hoist or maybe an engine hoist because it is very heavy as an assembled unit. It is flawless in its operation. Very well made. I am very happy with it.
So far this hitch has performed well. I have a Mor Ride hitch and had to purchase the adapter plate. The hitch connects well to the adapter plate which eliminates me having to use the adjustable side bars. The hitch is heavy but sturdy. I would recommend this hitch to anyone looking for a hands free sliding hitch.
Installation was straight forward operates very smooth and quiet installed overhead winch as seen in photo to make install easy also to remove very impressed with the craftsmanship of hitch.
I think that etrailer requires their employees to lie so as not to have any confrontations with customers on the phone. I placed two orders on 8/23 and immediately received followup emails that order received, order processed by (employee name) and then is in stock with associated time each step completed.
Then I noticed that shipping date kept getting 1 day later each day I checked order status. So, I contacted etrailer on day 5, 8/27 and find out my item was not in stock at all and would not be until mid Oct. Well,I then had them order me the same part by a different manufacturer and was told that it was in stock and would still be still be shipped 8/28 and delivered on 8/30, the same day my fifth wheel hitch is being delivered, so everything seemed rectified until I checked order status online the evening of 8/28 and find that the ship date again had been pushed back another day 8/29 with a delivery date of 9/1, (which is a Sunday). Seems that at this rate I may have it sometime in September. Going by their assurance of delivery on 8/30, I arranged to pickup my new camper on 9/5, that seems to be an impossibility at this time because Order #121389499 the installation kit with base rails is a very necessary part of the assembly. So, in closing I can only say that if you do not have the parts to ship, be honest and state the truth. This has made me feel very negative now toward etrailor as I already had become with Camping World. Is there any honesty in the RV parts aftermarket?
I had an auto sliding hitch made by a competitor. It wasn’t built anywhere near the quality of this hitch. This hitch is much smoother and far better quality of construction hands down it’s a better hitch.
Well built fifth wheel hitch. Haven't got a chance to tow our new Montana High Country 295RL. But I know a guy that has towed his fifth wheel with this same hitch. I'm sure this 18K hitch will be excellent! Or I wouldn't have bought it. I recommend e trailer for everything.
Great Product! I thought that I was not going to be able to use my DEMCO auto slider because the Rhino box pin box was too small on the new camper. This helps out perfectly! Customer support was great helping me find the right solution!
Product arrived as promised. It was packaged extremely well and secure. No damage or anything missing. I was impressed with the time frame in which it was delivered. Very happy with the order and delivery process. I installed it in my Chevy 2500 without any issues. It took me about 2 hours or so to install. The hardest part was accessing the bottom of the hitch to tighten up the 8 bolts that hold the sides on. You will need two people to set in the truck bed. I still need to install the support bar. You will need an extra bolt to screw into the threads to get rid of paint on the threads.
Seems to be built very well, and installation was fairly easy considering the size and weight. Won’t know how it travels until I get the RV in the Spring….we shall see! In my particular case, I had to use spacer washers between one of the brackets and the hitch so it wouldn’t jam in the truck mounts but no big deal.
I’ve also figured out a way to “store” the hitch for the winter.
After a year, I still like my Demco autoslide. It works great. I have pulled my trailer quite a few times and have had no issues at all. I know quite a few people that pull 5th wheels and one actually went out and purchased a autoslide after watching mine work.
I like the hitch the only down fall is the weight of it. When I need to remove it so I can use the back of the bed it not a 5 min job.
Installation was simple and straight forward into my Ram truck with the bed factory prep for the puck system. The unit was shipped the day I ordered it and delivery was only a few days. The unit is quite heavy so best to have two people available for the installation. It functioned perfectly the first time I used it!
LOVE, LOVE, LOVE IT. I purchased 2 different 5th Wheel Hitches before I purchased this one. After hitting the cab of the truck, I wanted to get a slider. I did my research for several months and just kept coming back to the Demco. This hitch automatically makes the adjustment when I need it, even when I don't realize I need the extra room. I never have to get out of the truck to release the hitch to slide back. I put the hitch together with no problems, of course it came about put together anyway, and the Instructions were good. the locking down ont he truck seems to be easier than other I had. The only regret I have is that I didn't buy this one sooner.
This 21K unit is very well built. It does have some weight to it so some help installing would be much easier.my installation was completed solo and took approx 1 hour in a GMC 3500 Denali.
Amy at eTrailer was great to work with. she helped me with hitch selection and followed up with questions about delivery. And when the delivery carrier damaged one of the boxes and lost some of the hardware, Amy sent a replacement ASAP.
